There are some tanks running solar tubes. Not sure how popular they are these days but they do produce some serious lighting if your home can accommodate them. Use whatever your favorite search engine is and you should come up with some examples. I've also seen a few tanks in sunrooms. Again, if set up properly there is enough natural light to work with that may only require some supplemental. Lastly, there are some folks here, at least one with an amazing tank, down in Southern California that run outdoor tanks. Impressive to say the least.
I think it comes down to what your budget is, solar power or lighting window (forget what the term is but it is used widely in solar. What your maximum power generating light and it would vary by geolocation), and what your goal(s) are. It is possible and then something simple has a window. That is what I do in the morning and have for a while. Open blinds, get direct light, and let it ride. Really just up to you.
